Vertical Shaft Impactor, VSI Crusher, Artificial Sand Making Machine

Product Description

Application
VSI crushers are widely applied in expressway and railway building, hydropower station construction, bridge and tunnel building, concrete batching plant, etc. for crushing and gravel shaping.
Main Features and Benefits It adopts high quality roller bearing like Sweden SKF and American TIMKEN, which ensure the smooth running of main unit. Unique feeding method (change between central feeding and central feeding with cascade feeding make "rock on rock" and 'rock on iron" possible, both crushing and shaping are achieved. Advanced double pump oil lubrication system minimize the maintenance frequency Hydraulic lift cap, easy and convenient replacement and maintenance Over vibration alarm system Special dustproof seal system prevent the dust from entering oil mouth Working Principle
The material enters the VSI crusher through hopper, which is divided into two parts. One part entering into the rotating impeller through the distributor at high speed, then is accelerated, and shot through the tunnels around the impeller at high speed. First part material will impact with other materials fallen from the material distributor, hit on the crushing chamber together, then will be rebounded and impact on the top of crushing chamber, Changes its direction and goes down, forms continual material layers with material shot from the impeller. Therefore some materials will be impacted, crushed, milled twice or more times in the crushing chamber, then crushed material will be discharged from discharging part.
